Just spent far too long on #CrackingTheCryptic May Patreon challenge grid 3. I couldn’t disambiguate it at all. I ended up clearing it and restarting, and I seemed to somehow not make the same mistake the second time around. Still took me 55 minutes though. But I do like this “Oil and Water” #Sudoku variant

Dites, les matheux, vous jouez à ces trucs de temps en temps ?

Je viens de publier mes archives de KDK Training et les programmes qui me permettaient de créer ces ebooks sur github.com/DeveloppeurPascal/K

Les codes sources en PHP sont de 2009.

Les PDF ont été publiés de 2009 à 2014 en diffusion gratuite. Ils servaient de support publicitaire pour des sites maintenant disparus sous forme de sponsoring.

One of the aspects I like about those #Sudoku solving videos with esoteric rules and few or no given digits is seeing where symmetry breaks. The setters often are drawn towards rotationally or laterally symmetric designs, or even something like German Whispers where high and low are interchangeable (so its value-symmetric, I suppose). But for a puzzle to uniquely solve, that has to break somewhere. I enjoy trying to spot it. #Puzzles
